To all whom it may concern Be it known that I, OTHO M. O'r'rn, a citizenof the United States, residing at the city of Jamestown, in the countyof Chautauqua and State of New York, have invented certain new anduseful Improvements in Sheet-' Metal Structures, of which the following,taken in connection with the accompanying drawings, is a specification.

The invention relates to sheet metal frames for doors and similaropenings in which the sheet metal has to be securely attached to thewall around the opening; and the improvement consists in providing asheet metal frame with means for securely attaching the same to a wallaround an opening by means of the plaster and also by means of hingedadjustable sliding anchors which may be turned to the vertical-positionfor shipmentand to the horizontal. position for anchorage in the wallas, for example, in the mortar between layers of brick or tile; and theinvention consists in the novel. features and combinations hereinafterset forth and claimed.

In the drawings, Figure 1 is an elevation of a sheet metal door framewith the, anchors in the folded position for shipment, the horizontalanchoring position being shown in dotted line, to which position theanchors drop when released from the shipping crate. Fig. 2 is aperspective elevation of one of the slotted adjustable holding platesthrough which the anchor is hinged, and for the sides of the channelshaped frame, the sheet metal frame being shown in dotted outline withthe holding plate in position'therein. Fig, 3 is a sectional view of aportion of the frame and one of the anchors in the anchoring horizontalpositionand supported upon its holding plate, the vertical or foldedposition being shown in dotted line. 4 is a perspectlve view of one ofthe sheet metal anchor plates as shaped by suitable dies from asinglepiece of metal, and Fig. 5 is a perspective view of asimilar'shaped'anchor plate built up of pieces of metal. Fig. 6 is a topplan view of one of the anchors in position, the wall engaging portionof the anchor being partially broken away and the holding plate anda'portion of the frame or jamb being Fig. 7 is a perspective view-of aportion of the inner side of the door jamb or frame with the anchorholding plates thereon showing the holding lugs for said plate as struckup from the sheet metal, otherwise giving a positive outline of theconstruction shown in Fig. 2. Fig. 8 is a crosswise sectional view ofthe door frame with the edge portion of the door in sectionthereagainst,and showing modifications of the construction of the anchorholding plates; and Fig. 9 is a perspective view of a furthermodification of said anchor holding plate. Fig. 10 is a perspective viewof the inner side of a portion of the door jamb or frame showingmodifications or different forms of blister or lug construction forholding the crosswise anchor plates within a limited space of adjustmenton the frame and also for engaging the mortar. Fig. 11 is a sectionalView of a portion of a tile built wall with the mortar on the oppositesides thereof showing its anchorage in the flanges of the sheet metaljamb or frame, with the crosswise anchoring plate in dotted line and theedge portion of the door in position against the jamb.

Like characters of reference'refer to corresponding parts in the severalviews.

The numeral 10 designates the sheet metal frame for a door, window orsimilar ,0 ening, which frame is made in channel orm with the sides 11and inturned flanged edges 12 which incline toward the inner wall of thechannel and away from the wall of the opening.

The inwardly inclined flanged edges 12 support thereon in slidableadjustment the anchor holding plates 13, preferably between .the struckout lugs 14 in order to space said anchoring plates 13 and at the sametime permit their adjustment to the joints in the wall as the same isbuilt up around the frame 10. The struck out lugs 14 may be made indifferent forms, as shown at 14:, 15, 16 and 17 and attain the purposethough the outwardly projecting dovetailshaped' lugs 14 are preferredsince the body of the lug projects into and is surrounded by the mortarand assists in anchoring the side 11 of the sheet metal frame wall andat the same time provides an opening 18 through which the mortar 32 isforced, thus binding or interlocking with the wall when the plaster 32hardens.

It is obvious tothe correct construction of a door or window jamb thatits sides should be plumb. Accordingly the cross holding plates 13 areplaced at spaced intervals along the inner side of the frame 10' againstthe serving the double purpose of holding the sheet metal sides 11 incorrect spaced rela. tion from one another and at the same t1meproviding in the lengthwise slot 19 an opening through which the end ofan anchor plate 20 may be inserted. In order that the anchors 20 uponeach side of a door frame 10 shall occupy as little space as possibleduring shipment they are made to fold ver tically against the outersides of the frame 10 so that they will drop into the horizontalposition for anchorage in the wall as soon as released from the shippingcrate and placed upright.

The anchors 20 are made in the angular form to hinge them to the frame10, a brace 21 being struck out from the sheet metal or attached theretoto hold the anchor 20 firmly in said angular form. The upper end of theangular portion 21 is turned in lugs 23 and 24: when made from one pieceof sheet metal,

or when built up from several pieces as:

shown in Fig. 5, the lugs 23 and 24 may be continuous across the end ofthe angular anchor plate. The Wall portion 25 of the anchor preferablywidens out dovetail shaped, and its sides are preferably turned inangular flanges, thereby'giving a shallow channel shape to the portion25 which when filled with mortar firmly anchors the end 25 in the wallgiving great rigidity to the frame 10.

It is apparent that the lugs 23 and 24 may be inserted through slot 19of the an chor holding plate 13 before the lug 24 is turned into itsholding position, being bent upward after said insertion so that thelugs 23 will hold against the inner side of the holding plate 13 belowthe slot 19 when the anchor 20 is in the folded position and the lug 24;will hold against the inner wall of the cross plate 13 above the slot 19when the anchor 20 is in the horizontal position for anchorage in thewall, thus providing the limited hinge movement desired for the anchors2 0 and at the same time permitting them a sliding vertical adjustmentupon the frame: 10, the ends of the plate 13 being formed with the lugs26 and 27 for engag ing on the opposite sides of the inwardly extendingflange 12. The anchor holding plate 13 is preferably made with the topand bottom flanged edges 28 to stifi'en the same and at the same timeprovide a channel construction which holds more firmly in the plasterwhen built into the wall. Said fiangesare-usually shaped as shown at 28in Figs. 9 and 10 though they may be given the modified form as shown at29 in Fig. 8 in which the flange edges 29 extend out over the inturnedflanges 12 and perform the ofiice of the'lugs 26 in holding the plate 13upon the flanges 12.

It is also apparent that a narrow holding bar as shown-in the modifiedform 30 may be used though not as strong or serving as good a purpose inholding-the anchors 20.

It does, however, keep the channel sides 11 of the frame 10 fromspreading and combined with the plaster holds the frame sides 11 in linethereby partially attaining my purpose though not as efiiciently as bythe slotted holding plate 13. lhe ends 31 of the plate 30 are insertedthrough the openings 18 and bent toward one another to form a stronghooked holding construction.

The bent out loop 15 or blister 17 or turned corner 16 form projectionswhich limit the sliding adjustment of the plate 13 and also provideopenings through which the plaster may be inserted to assist in theanchorage of the frame but they do not provide the anchoring projectioninto the mor-- tar which enlarges outwardly thereby forming a strongholding attachment as in the case of the struck'up lugs 14.

I claim as new 1. In combination with a channel shaped metal framehaving inwardly extending sides with the outer edges thereof free, across bar having its ends formed with angular parts to engage over saidouter edges of the sides, so as to prevent relative spreading of thelatter, said sides having their free edges provided with slits and themetal to one side of the slits being bent outwardly and displacedtherefrom to engage and support said bar and to extend into the mortar.

2. In combination with a channel shaped metal frame having inwardlyextending sides with the outer edges thereof bent inwardly at acuteangles free, a cross bar having'its ends formed with angular parts toengage over the inner and outer faces of said outer edges of the sides,so as to prevent relative spreading of the latter, said sides havingslits therein and the metal adjacent the slits being displaced so as toproject outwardly from the sides to engage and support the bar and toalso extend into the mortar, the slits in) also forming openings toreceive the mortar.

3. In combination with a channel shaped metal frame having inwardlyextending sides, a cross plate having a pair of longitudinally extendingslits at each end thereof to form-lugs, the lugs on the outer sides ofthe plate being bent outwardly and the central lug being'bent inwardlyin the opposite direction so as to receive the frame sides between thelugs.

4 In combination with a channel shaped metal frame having inwardlyextending sides, a cross plate having a pair of longitudinally extendingslits at each end thereof to form lugs, the lugs on the outer sides ofthe plate being bent outwardly and the central lug being bent inwardlyin the opposite direction so as to receive the/frame sides beiii slitsbeing displaced to project outwardly and engage the lugs on the adjacentside of the bar. I i

5. In combination with a channel shaped metal frame having inwardlyextending sides, a longitudinally slotted cross plate connected to saidsides, anchor plates, and means to hingedly connect the anchor plates tothe cross plates consisting of a member extending outwardly from theanchor plate at substantially right angles thereto and adapted to engagethe front face of the cross plate to hold the anchor plate at an anglethereto, a lug extending parallel to said member to engage the innerface of said cross plate and a lug extending at an angle to said memberto engage the rear face of said cross plate to limit the upward movementof the anchor plate when the latter is folded to lie in inoperativeposition.

6. In combination with a door or window frame, anchor plates, means toconnect said plates to the frame comprising a hinged oint to permitfolding of the plates against the frame for shipment and to permitunfolding of the plates to lie at substantially right angles to theframe, and means to hold the plates against downward movement when atright angles to the frame.

7. In combination with a channel shaped metal frame havin inwardlyextending sides, a longitudinally slotted cross plate connected to saidsides, anchor plates, means borne by the anchor plates and engaged inthe slots of the cross plates to provide a hinge connection between theanchor plates and the cross plates so as to permit the anchor plates tofold against the cross plates, and means to limit the downward movementof the anchor plates upon unfolding of the latter so as to hold theanchor plates at substantially right angles to the cross plates.

8. The combination of a channel shaped door or window frame, lengthwiseinturned inwardly inclined flanges along the opposite edges of saidchannel shaped frame, holding plates having a lengthwise slot therein,oppositely turned lugs on the ends of said hold ing plates to slidablyengage said inturned flanged edges, spaced projections on said inturnedflanged edges to space said holding plate, angular dovetail shapedanchor plates having flanged edges to hold in the mortar of the wall,and lugs on said anchor plates at right angles to one another to formstops for said anchor plates in the folded and extended position wheninserted through said holding plates. I

9. In combination with a channel shaped metal frame having inwardlyextending sides with the outer edges thereof free, a cross bar havingits. ends formed to engage over said outer edges of the sides, so as toprevent relative spreading of the latter, and spaced means integral withthe frame sides and extending out therefrom to engage and limit theupward and downward movement of the bar, said bar being slidable betweensaid spaced means and the latter being formed to project into the mortarand to provide mortar receiving parts.

10. In combination with a channel frame having spaced side flangesconverging toward their free side edges, a cross brace extending acrossthe space between said side flanges, and spaced means on the cross braceto engage on opposite side faces of the respective side flanges toprevent relative spreading thereof, said means of the cross brace beingformed so as to be movable along the lengths of said side flanges of thechannel frame.

In testimony whereof I have affixed my signature in the presence of twowitnesses.
